Presents a description of the development of a laboratory-oriented chemistry course and the results noticed when the course was implemented. The syllabus was considered to be highly successful. (EB)

Presents an alternative series of investigations replacing the propanone-trichloromethane system (Topic 10) in the Nuffield A-Level course. A trichloromethane-ethyl ethanoate (acetate) system presented in four experiments give good results and removed the dangers arising from the other system. Topic 10 need not be re-written, just the replacement…

Describes a course designed to teach the fundamental microbiological principles common to all disciplines. The course is designed to meet individual student needs through self-directed lab work and various minicourses on topics in applied microbiology. (GS)

This document presents a model for a simple transmission electron microscope for educational purposes. This microscope could demonstrate thermonic emission, particle acceleration, electron deflection, and flourescence. It is designed to be used in high school science courses, particularly physics, taking into account the size, weight, complexity…

Based on experiences gained through involvement with three curriculum development projects, one relating to an elementary science curriculum and the other two relating to junior high school mathematics, the following recommendations are presented: (1) financial support from an outside agency, public or private, makes boldness more probable in…

This address presents the results of a nationwide survey of science educators throughout Australia, including teachers, curriculum workers, and teacher educators. These educators were asked to comment on three categories related to science education: (1) past trends, (2) aims, and (3) future trends. Results of the past trends questions indicate a…

This syllabus presents material to be covered in chemistry for pupils of varying skills and abilities in New York public high schools. An outline of topics provides an overview of the principles, concepts, and applications included within the course and tested in the New York State Regents Examination. Twelve units of study are described. Material…

Described is the ninth- through twelfth-grade science program of the Montgomery County Public Schools, Rockville, Maryland. This program provides opportunities for students to experience individual interests and career choices. Two credits in science are taken in grades nine through twelve and generally include laboratory science and biology. Most…

A YEAR COURSE IN NINTH-GRADE SCIENCE WAS IMPROVED BY THE EVALUATION OF EACH LESSON USING A LEARNING PROFILE STUDENT RATING TECHNIQUE.THE PURPOSES OF THE STUDY WERE TO MAXIMIZE EFFICIENCY OF SCIENCE INSTRUCTION, TO MEASURE IMPROVEMENTS, TO TEST EFFECTIVENESS OF NEW MATERIALS, TO SUGGEST WAYS OF IMPROVING INSTRUCTION, TO EVALUATE ACTIVITIES ON A…

THE PURPOSE OF THE STUDY WAS TO DETERMINE THE RELATIONSHIP BETWEEN STUDENTS' ACHIEVEMENT ON BEGINNING CHEMISTRY AND THEIR BACKGROUND PRIOR TO ENROLLMENT IN THE COURSE. OF THE 609 STUDENTS ENROLLED IN BEGINNING CHEMISTRY IN THE 1964-65 ACADEMIC YEAR, 45 PERCENT RECEIVED GRADES OF A, B, OR C. OF THE GROUP STUDIED, 23 PERCENT WERE REPEATING THE…

This teacher's guide suggests a number of ways to use a spinning table to explore circular motion. Activities are described which are appropriate for children in kindergarten through third grade. Suggestions are made for exploratory activities using the equipment rather than supplying detailed instructions for formal activities. Equipment and…

Presented are building activities, for elementary school children, using a variety of different materials. Weak materials, such as clay, straws and pins, paper tubes and index cards, are used as examples; structures built with these materials are displayed in photographs and discussed. Problems are suggested from which additional activities can be…

Presented is a two-year associate degree curriculum for Engineering Technology. Specializations are provided in civil, electronics, and mechanical technology. The civil engineering technology specialization facilitates three major areas of study, and mechanical technology includes design and production options. Each curriculum was designed to…
